ELECTRONIC CONTROL
The device is equipped with a multi-level battery monitor that protects your vehicle battery against excessive
discharging when the device is connected to the on-board DC supply.
If the cooler is operated when the vehicle ignition is switched off, the cooler switches off automatically as
soon as the supply voltage falls below a set level. The cooler will switch back on once the battery has been
recharged to the restart voltage level. The compressor will start up again automatically when the voltage
goes back to normal values.
Note: these values are measured at control unit input and/or on the DC socket.
NOTICE! DANGER OF DAMAGE!
When switched off by the battery monitor, the battery will no longer be fully charged. Avoid starting
repeatedly or operating current consumers without longer charging phases. Ensure that the battery is
recharged.
BATTERY PROTECTION LEVEL
It is possible to set three different battery protection threshold levels:
BATTERY
PROTEC-
DISPLAY
TION
LEVEL
1 Bar
LOW
2 Bars
MED
HIGH
3 Bars
The device is preset with a medium battery protection level.
To enter the menu, switch the refrigerator on by pressing the ON/OFF button.
Press and hold the SET + ON/OFF buttons at the same time for several seconds to access the battery
protection level setting. The current setting will start to flash on the display.
Press the SET button a number of times to scroll through the three different settings:
1 Bar
2 Bars
3 Bars
Without having to press any other button to confirm, the display will automatically save the setting and exit
programming mode.
NOTE
When the cooler is supplied by the starter battery, select the battery monitor mode "HIGH". If the cooler is
connected to a supply battery, the battery monitor mode "LOW" will suffice.
